Definitions

  • the invention relates to a method according to the preamble of claim 1 and a respiratory therapy device according to the preamble of claim 2.
  • Such devices are used for the treatment of obstructive sleep apnea.
  • Another application is the prevention of snoring.
  • CPAP devices Continuous Positive Airway Pressure
  • CPAP Continuous Positive Airway Pressure
  • These devices provide respiratory air in a face mask, the pressure of which is continuously increased by a few hPa from the atmospheric pressure. When a patient breathes in this artificial atmosphere, his respiratory passages remain stretched wide enough due to the positive relative pressure to breathe.
  • a CPAP device thus only causes a "pneumatic splint" of the respiratory tract.
  • the breathing process itself is based solely on self-breathing.
  • Snoring is an indication of sagging and constricted airways.
  • the air pressure drops there, because with increasing speed, the distance between the L-molekülen becomes larger.
  • collapsed tissue collapses and obstructs the airway completely.
  • the flow-induced negative pressure disappears, the respiratory tracts straighten up and the air flows again until it reaches a certain speed. This leads immediately to the next closure.
  • Fast snoring of the occlusion and opening of the respiratory tract causes the snoring sound.
  • a CPAP device increases the air pressure relative to the atmospheric pressure (relative pressure) so far that the flow-induced pressure reduction can no longer cause a closure and thus prevents the formation of a snoring sound. If the underlying snoring mechanism exceeds a certain severity, then also the respiratory drive. Now there is the disease "obstructive sleep apnea" in need of treatment, which affects at least 1% of the population. The disease is mainly treated with CPAP devices. Mechanical aids or surgical interventions are additional but minor therapeutic options.
  • a disadvantage of known CPAP devices is that they have an internal flow resistance, which the patient must overcome with his respiratory muscles. This results in an additional burden, because the internal resistance of the device adds up to the airway resistance of the patient.
  • CPAP devices are therefore equipped with an integrated humidifier or the humidifier is switched on as an additional device between the CPAP device and the patient.
  • Other disadvantages of CPAP devices include operating noise, disability through the face mask, hygienic risks and high energy consumption.
  • EP-A-0 330 740 also known as an artificial respirator, which, among other things, also treats sleep apnea and which consists of a bell and a blower, both of which are connected to one another via supply lines. These supply lines incorporate technical valves and control devices for influencing the function of the blower.
  • the bell is placed on the chest of a human body and creates a rhythmic change between a negative pressure and an overpressure within the bell. This rhythm is tuned to the natural breathing rhythm of the human, so that the breathing process is actively supported.
  • the main disadvantage of this ventilator is that it is not suitable for the prevention of snoring sounds.
  • the invention is therefore an object of the invention to provide a generic method and a corresponding respiratory therapy device that allows breathing in a free atmosphere. Further tasks include the abolition of the face mask, the reduction of operating noise, the improvement of hygiene and the reduction of energy consumption.
  • the respiratory therapy device no longer supply the breathing air, but only has to maintain the negative relative pressure in a chamber, the breathing tube in favor of a thin suction tube is also eliminated.
  • the suction fan does not have to move large amounts of air, but only the amount that flows as a result of leaks in the vacuum chamber.
  • the required power of the suction fan is so small and can also be applied by a battery.
  • the whole fan can be kept quite small, whereby a good soundproofing is made possible.
  • Benefits also arise in the security sector. Failure of the blower will not automatically result in CO 2 rebreathing. In such a case, the symptoms of obstructive sleep apnea would be restored, but more could not happen. Hygienic advantages arise because no accessories such as hose and mask are flowed through by the breathing air and thus no more condensation can form. The time cleaning cycle can therefore be essential be enlarged. Use of the device by different patients is harmless.
  • the device Since the device is simple in construction and inexpensive to manufacture and there are no dangers associated with its use, it can also be used without a medical prescription, for example to prevent snoring.
  • a medical prescription for example to prevent snoring.
  • the devices usually consist of an object that must be worn in the mouth or on the teeth. This can easily cause accidents when, for example, the used anti-snarl brace dissolves and is swallowed.
  • the example device consists of a neck mask 1, a suction tube 2 and a suction pump 3.
  • the neck mask 1 is a half-open chamber which dome-shaped spans the anterior (ventral) neck region.
  • the edge of the neck mask 1 circumscribes the region starting from the chin on both sides of the lower jaw along the sides of the neck and from there forward again down to the upper end of the sternum.
  • a sealing device 6 is arranged, which rests on the skin in use. In this way, the open side of the neck mask 1 is closed by the skin of the patient and a closed chamber volume 7 is formed.
  • the surface of the neck mask is such that it is stiff perpendicular to its surface but flexible in the direction of extension of the surface.
  • the mask surface can enlarge and reduce during pitching movements of the head and laterally distort during rotational movements of the head.
  • this property is achieved in that the shell of the neck mask 1 consists of an elastic skin 5, for example of rubber or other elastomer over a base of stabilizing skeletal clips 4.
  • a nozzle-shaped air outlet 8 is arranged which leads from the outside through the shell of the neck mask 1 into the closed chamber volume 7 and which is connected to the suction side of the suction pump 3 via the suction hose 2.
  • a neck hand 9 is provided, which could also be provided with a closure, preferably with a hook and loop fastener.
  • the suction pump 3 During use, the suction pump 3 generates a constant negative pressure of a few hPa via the suction hose 2 connected to the air outlet 8 in the closed chamber volume 7. This is achieved by a pressure-controlled suction pump or by setting a specific speed on a suction fan. If there are leaks between the skin of the patient and the sealing device 6, the leakage volume flowing into the closed chamber volume 7 is sucked off. Also head movements cause no change in the negative pressure in the closed chamber volume 7 when the suction pump 3 or the suction fan used have a device for pressure control.
  • the neck mask 1 spans the entire ventral neck region and at this point produces an artificial negative pressure atmosphere with the closed chamber volume 7, the respiratory tracts of the patient are splinted by the pressure of the normal atmosphere. Flow-related pressure drops in the throat area of the patient no longer lead to collapse of the respiratory tract. Snoring sounds can not arise anymore. Patients with obstructive sleep apnea can breathe freely and have a healthy sleep again.
